Jane Foster is revealed as the mysterious masked woman who has been swinging Mjolnir as Thor since the Dude Formerly Known as Thor — now just called the Odinson — was deemed unworthy.
After Mjolnir deems Jane worthy of carrying it for herself and bearing Thor's powers, she is primarily known as the Mighty Thor. While many have called her Lady Thor, this is a name that both the character within Marvel Comics and the MCU has fought back against.
However, the film also implies that the hammer only sees Jane as worthy because Thor unintentionally revised the rules of Mjölnir, giving it the power to protect her. Captain America didn't need anything special for the hammer to see him as worthy – he's able to wield it without issue in Avengers: Endgame.
During that long history, he has been pictured in intimate moments with all kinds of women, including all the women in a village and his sister Hela who wanted a baby. Even though many count Thor as a ladies' man, there have only been about 8 times where feelings were involved.
Jane Foster made her first appearance in Journey Into Mystery #84 back in 1962. She initially had the last name “Nelson” and was created as a love interest for Dr. Donald Blake, the secret human identity of Norse god Thor.

Why is Mighty Thor not Lady Thor?
Marvel Rightly Refused To Call Jane Foster Lady Thor
Marvel continues to reiterate that Jane is Mighty Thor as a way to prove that this isn't just a female version of Hemsworth's superhero. By wielding Mjolnir, Jane becomes Thor in the same way that Sam Wilson becomes Captain America after taking control of the shield.
Mighty Thor is not a Thor “variant” or a Thor from another universe but is rooted in an original comics storyline. After Nick Fury whispers something to Thor which renders him unworthy to wield Mjolnir it opens the opportunity for another to wield the weapon and thus possess the power of the God of Thunder.
Mysteriously, the broken pieces of Mjolnir, the hammer of the thunder god, transformed her into the Mighty Thor and gifted her the superpowers of Thor, to battle threats internal and external. Wielding Mjolnir herself, she had become a godly protector and a new hero was born!
Jane Foster has deep roots in the Marvel Comics. Here's how it all began. Thor: Love and Thunder's most intriguing storyline involves Natalie Portman's Dr. Jane Foster and her empowering transformation into a female version of the hammer-wielding god.
Even though this was a “What If” story from a slice of the Marvel Multiverse, the issue predicted what would later come to pass. Jane, her identity unknown at the time, was introduced as the all-new Thor in THOR (2014) #1 after Thor was deemed unworthy after the event ORIGINAL SIN.
second reason for this is a bit technical mjolnir basically strengthens the cells of jane foster to make her thor.. in this process her cancer cells also gets strengthens plus chemotherapy which acts as a acid to those cells mjolnir this it's causing harm to her body so it Wipeout the chemotherapy from her body...
In the comics, it is explicitly stated that Jane's cancer progresses because the transformation that Mjölnir causes in her thinks it is healing her: namely, it purged the drugs from her chemotherapy treatments because those are technically foreign toxins meant to kill cells.
Stormbreaker has the additional power to summon the Bifröst, allowing Thor to teleport anywhere in the Nine Realms. Screen Rant has identified Stormbreaker as the more powerful of the two, based on this ability, as well as it being a much larger and edged weapon.
The helpful drugs were subsequently emitted, so Jane's condition worsened as cancer spread throughout her body. She eventually sought help from Doctor Strange, one of the few people who knew her true identity. He advised her to stop transforming into Mighty Thor as the next time could kill her.
Torunn is the daughter of Thor and Jane Foster. She's a member of the Next Avengers. When she was a a child she's been looked after by her mother after Thor leaves on an important mission. After growing up she wants to know who and what is she and whats her father like.
When it comes to the most powerful character out of Mighty Thor and Thor Odinson, the latter comfortably wins. Thor Odinson has proven himself as the most powerful due to everything that he has been through during his eight MCU appearances.
Upon saving Asgard from Ragnarok, Odin forces her to relinquish the hammer to Donald Blake so he can become the new Thor. This resulted in Jane losing her powers, but she was allowed to remain on Asgard and keep her goddess status since she later falls in love with and marries Thor.
This means that it's very likely that Jane Foster could return, creating hope that other characters in Valhalla could come back too. While not much is known about who is currently in Valhalla, Idris Elba made an appearance as Heimdall, who died during Avengers: Endgame, so it's possible he could return too.
However, it would seem that what went wrong between Jane Foster and Thor is most likely tied to Thor's status as an Avenger and a god who only comes to Earth when duty compels him, which had been seen to cause tension between the pair leading up to Thor: The Dark World.
She was ultimately resurrected by the cosmic entity Eternity in accordance with Gorr's wish, brought on by Thor's advice. She was left in the care of Thor by Gorr before he died, leading her to become Thor's ward and adoptive daughter. The pair began protecting alien species, becoming known to many as Love and Thunder.
Thor's wife was Sif, a golden-haired fertility goddess, with whom he had a daughter, Thrudr (Strength). He was also the father of two sons, Modi (Courage) and Magni (Strength), by Jarnsaxa, a giantess, and stepfather of Sif's son Ull.
Over 12 issues, Thor is defeated multiple times by the five new Phoenix hosts: Cyclops, Colossus, Emma Frost, Namor, and Magik. At one point, Colossus is even able to smash Mjolnir away from Thor's hands, proving Phoenix is a strong force not to be messed with.
Natalie Portman as Jane Foster / Mighty Thor: An astrophysicist and Thor's ex-girlfriend who is undergoing cancer treatment and who gains powers to become the Mighty Thor by wielding a reconstructed Mjolnir, the hammer previously wielded by Thor.
